Migrating to HCS with Wrangler - Deep Dive

Overview

Wrangler automates the time consuming and error prone activities during a migration the helps HCS partners reduce cost and onboard customers faster.

As no two UC migration are the same, a high degree of customisation and variation in the migration process is required to suit all customer requirements. Wrangler simplify and improve UC migrations by providing the following:

Consistent migration process with a single pane of glass

Telephony data extraction from on premise systems

Automated data cleansing and validation

Centralised customer data verification

UC Project issues management

Generation of bulk loaders and automated API upload

The Wrangler engineer toolkit provides deployment teams with a variety of tools that make deployment teams more efficient by providing

Customisable data extraction and reporting from source systems using a web-based SQL browser

Real time status and local endpoint configuration reporting to find anomalies in source systems

View current Extension mobility (EM) status and make bulk changes such as login or logout

Extract and compare LDAP information

Usage analysis based on CDR history

Automatic number range instantiation

Number normalisation for speed dials, call forwards and LDAP directories

Endpoint management (backgrounds/ringtones/ITL)

Now lets get into the details

Wrangler was designed to suit the HCS environment where multiple customers are migrating at the same time and provide a single management interface but still be able to reach out to the customer systems without requiring static NATs

Wrangler can import from multiple CUCM's and LDAP sources

Wrangler Support CUCM 8.6+

Create and normalize sites either via regex or drag and drop

Normalize CSS names

Now import that cluster

Note how approx 1000 devices is imported in 1 Minute as we use SQL rather than AXL

Wrangler automatically finds devices and users that have issues such as external mask, primary line and devices

These items typically need manual attention validation

Wrangler also does auto fixes for device association for licensing and masks

Normalization

Number Ranges

Wrangler will automatically instantiate the number ranges based on the data imported

Phone Button Templates

Wrangler will automatically de-duplicate and normalise the name for PBTs

Speed Dials

Wrangler will parse all Speed dials and convert to e164, it also caters for on net dialling and varible PSTN break out

Wrangler will also normalize the Call forward destinations like speed dials

Manual Queries

These allow for easy data extraction from SQL, RIS, LDAP and EM

The RIS query also allows for resetting ITL/CTL during a migration from the source system as well as finding any phones with alternate TFTP set that will cause issues with the migration

It will also soon support background and ringtone deployment

Transforms

Wrangler can transform existing data to add new devices such as hybrid, replace existing device, change usernames to suit SSO or re-numbering
